13252-15-8 Usage
General Description
Perfluoro-2,5,8,11,14-pentamethyl-3,6,9,12,15-pentaoxaoctadecanoyl fluoride is a chemical compound commonly found in industrial applications. It is characterized by a combination of fluorine and carbon atoms, which contribute to its stable and highly resistant nature. Due to these properties, it is often used in the production of various synthetic materials and products. However, the compound exhibits potential to bioaccumulate and has been linked with several health and environmental hazards. Substantial exposure to this chemical may incur adverse health effects in both humans and wildlife. Regulatory measures are in place to control its use and to mitigate potential risks associated with it.
Check Digit Verification of cas no
The CAS Registry Mumber 13252-15-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,2,5 and 2 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 13252-15:
(7*1)+(6*3)+(5*2)+(4*5)+(3*2)+(2*1)+(1*5)=68
68 % 10 = 8
So 13252-15-8 is a valid CAS Registry Number.

Radical additions to fluoro-olefins. Photochemical mono-fluoroalkylation and sequential bis-fluoroalkylation of oxolane
Paleta, Oldrich,Cirkva, Vladimir,Kvicala, Jaroslav
, p. 125 - 134 (2007/10/03)
Oxolane was fluoroalkylated by its photoadditions under atmospheric pressure. Monofluoro-alkylations were carried out with hexafluoropropene (1) and perfluorovinyl ethers C3F7O-[CF(CF3)CF2O]n-CF=CF2 (2-4, n=0-2) by direct photoexcitation of the oleflns to give high yields of addition products 9-12 (81-94%). The reactions were completely regioselective at the oxolane molecule and almost completely regioselective (93-99%) at the double bond of fluoro-olefins; no bis-fluoroalkylated oxolanes were detected. The completely selective introduction of a second fluoroalkyl into position 5 of the oxolane molecule was accomplished by acetone-sensitised photoaddition of 2-fluoroalkylated oxolanes 9, 10 to fluoro-olefins 1 and 2. Byproducts from reactions of the dimethylketyl radical which is formed in the initiation step were isolated and have given some evidence about the reaction mechanism that is discussed.
